Abstract (en)
An embodiment of the present invention provides a method for a wireless communication apparatus including a plurality of antennas to transmit and receive a wireless signal in an unlicensed band in a wireless communication system, the method including: performing CCA(Clear Channel Assessment) using the plurality of antennas for a predetermined time duration in the unlicensed band; and if the unlicensed band is determined as an idle state where the unlicensed band is unoccupied by other communication apparatuses, transmitting a wireless signal through the unlicensed band, wherein the performing of CCA may include: obtaining one reference value using energy sensing indicators (ESIs) measured through the plurality of antennas; and determining whether the unlicensed band is idle by comparing the reference value with a CCA threshold.
